fromJson static method

DVMutation fromJson(Map<String, Object?> json)

A mutation as it arrived. The caller decides whether to trust it: a device names its own table and key, and nothing here checks either.

Implementation

static DVMutation fromJson(Map<String, Object?> json) {
  final Object? base = json['base'];
  return DVMutation(
    mutationId: '${json['mutationId']}',
    sequence: (json['sequence'] as num).toInt(),
    table: '${json['table']}',
    op: '${json['op']}',
    key: json['key'] as Object,
    values: (json['values'] as Map<Object?, Object?>? ??
            const <Object?, Object?>{})
        .map((Object? k, Object? v) => MapEntry<String, Object?>('$k', v)),
    deviceTime: DateTime.parse('${json['deviceTime']}'),
    correctedTime: DateTime.parse('${json['correctedTime']}'),
    base: base is Map<Object?, Object?>
        ? DVRecord(
            key: base['key'] as Object,
            version: (base['version'] as num).toInt(),
            values: (base['values'] as Map<Object?, Object?>? ??
                    const <Object?, Object?>{})
                .map((Object? k, Object? v) =>
                    MapEntry<String, Object?>('$k', v)),
          )
        : null,
  );
}
